Microsoft Azure Security Center

When you have your Hybrid Cloud Enterprise Design ready in a Microsoft HUB-Spoke model and your Security in place, you can do your optimize on your Azure workloads and keep up-to-date for your compliancy. Microsoft Azure Security Center can support you in Security and Compliancy (GDPR). Here you see my former blogposts about Microsoft Azure HUB-Spoke model architecture and Security by design :

Security in software is always on the move and changing in this world, when you think you are ready something has changed already. That’s why I love Microsoft Azure Security Center to keep you posted and giving you advise on Security but also on Compliancy.

From here you see a high-level overview of these new possibilities in Microsoft Azure Security Center :

Microsoft Azure Secure Score Dashboard

Microsoft Azure Security Center is working with Overall Secure Score. In my Test LAB we have some work to do 😉
The Azure secure score reviews your security recommendations and prioritizes them for you, so you know which recommendations to perform first. This helps you find the most serious security vulnerabilities so you can prioritize investigation. Secure score is a tool that helps you assess your workload security posture.Improve your secure score in Azure Security Center

Azure Security Center Recommendations

Microsoft Azure Security Center gives you advise to make your Security Score higher and you can improve immediately.

Microsoft Azure Hub-Spoke Architecture

This Enterprise reference architecture shows how to implement a hub-spoke topology in Azure. The hub is a virtual network (VNet) in Azure that acts as a central point of connectivity to your on-premises network. The spokes are VNets that peer with the hub, and can be used to isolate workloads. Traffic flows between the on-premises datacenter and the hub through an ExpressRoute or VPN gateway connection.

We only use the Azure Private peering

For this Hybrid Cloud Strategy we made four Microsoft Azure Subscriptions via the EA Portal :

The naming convention rules and restrictions for Azure resources and a baseline set of recommendations for naming conventions. You can use these recommendations as a starting point for your own conventions specific to your needs.

The choice of a name for any resource in Microsoft Azure is important because:

It is difficult to change a name later.

Names must meet the requirements of their specific resource type.

Consistent naming conventions make resources easier to locate. They can also indicate the role of a resource in a solution.The key to success with naming conventions is establishing and following them across your applications and organizations.

Azure connectivity and RBAC Identity

This tenant is federated with via ADFS and Azure Connect to Office 365. Identity management is provisioned
via Microsoft Identity Manager 2016 (MIM2016). With this already in place, we can Configure Microsoft Azure RBAC in the subscriptions.

Access management for cloud resources is a critical function for any organization that is using the cloud. Role-based access control (RBAC) helps you manage who has access to Azure resources, what they can do with those resources, and what areas they have access to.

RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management of resources in Azure.

Business Development

For Business Development we have a separated Active Directory in one forest and also federated via ADFS to Microsoft Office 365. For this environment we build one Azure subscription with a temporary Site-to-Site VPN connection to On-premises datacenter for the “Lift and Shift” migration via Azure-Site-Recovery (ASR)

S2S VPN IKE v2 tunnel with Cisco and Azure.

Azure Virtual Networks

Next step is to build the connections between the Azure HUB Subscription and the Azure Spoke subscription(s) when every Microsoft Azure subscription has It’s own Virtual Network (VNET). This is called VNET peering.

Virtual network peering enables you to seamlessly connect two Azure virtual networks. Once peered, the virtual networks appear as one, for connectivity purposes. The traffic between virtual machines in the peered virtual networks is routed through the Microsoft backbone infrastructure, much like traffic is routed between virtual machines in the same virtual network, through private IP addresses only. Azure supports:

The VNET Peering between Azure HUB subscription and Spoke 1 is Connected.

In this order you have to make the other VNET Peerings from the Azure HUB subscription to the other Spoke Subscriptions so that the network connectivity between VNETs is working. Because we have the Azure Internet Edge in the HUB for the other subscriptions.

In the Azure Reference Architecture we also do Security by Design in the Cloud with Firewall and Azure Network Security Groups (NSG) and every Azure component get it’s own Tag for Security Groups and Billing – Usage.

Azure Storage

In every Microsoft Azure Subscription (HUB and Spoke ) we created a Storage Account. You can choose for different kind of storage in Microsoft Azure.

Durable and highly available. Redundancy ensures that your data is safe in the event of transient hardware failures. You can also opt to replicate data across datacenters or geographical regions for additional protection from local catastrophe or natural disaster. Data replicated in this way remains highly available in the event of an unexpected outage.Secure. All data written to Azure Storage is encrypted by the service. Azure Storage provides you with fine-grained control over who has access to your data.Scalable. Azure Storage is designed to be massively scalable to meet the data storage and performance needs of today’s applications.Managed. Microsoft Azure handles maintenance and any critical problems for you.Accessible. Data in Azure Storage is accessible from anywhere in the world over HTTP or HTTPS. Microsoft provides SDKs for Azure Storage in a variety of languages — .NET, Java, Node.js, Python, PHP, Ruby, Go, and others — as well as a mature REST API. Azure Storage supports scripting in Azure PowerShell or Azure CLI. And the Azure portal and Azure Storage Explorer offer easy visual solutions for working with your data.

Deploying Azure IaaS Virtual Machine with ARM Templates

Enterprise organizations with more then ten employees managing IT datacenters are working by process and order to do the job for the business. When they are all using the Azure Portal and deploy Virtual Machines manually you will get a mess and things can go wrong. In Microsoft Azure you have the Azure Resource Manager for deploying JSON ARM Templates. With these Azure Resource Manager Templates you can automate your workload deployments in Microsoft Azure. For example : We build a JSON template to deploy a Windows Server in the right Azure Subscription in the right Azure Resource Group and with the following extensions to it :

Using with our Azure naming conventions and Azure policy we always deploy consistent without making mistakes or by wrong typing in the Azure portal. When you write and make your ARM templates for different workloads, you can store them in Azure DevOps Repo ( Repository) and you can connect your private repo to GitHub.

Making ARM templates works really Awesome with Microsoft Visual Studio Code which is opensource and free of charge. You can add your favorite VSC extensions to work with like Azure Resource Manager.

Azure monitoring and Recovery Service Vault

To manage your Azure Hybrid Cloud environment you have to monitor everything to keep in control of your Virtual Datacenter. And of course you have to plan your business continuity with Azure Recovery Services (Backup) by Design. We made in every Azure Subscription an Azure Recovery Services Vault for making Backups. This is because you don’t want backup traffic over your VNET peering’s. In the Azure HUB subscription we made a second Azure Site Recovery (ASR) Vault for the “Lift & Shift” migration of On-premises Virtual Machines to the landing zone in Azure HUB.

With Microsoft Azure Monitor we use Log Analytics and Service maps and with the same OMS agent on the Virtual Machine, we still can use Microsoft System Center Operation Manager (SCOM) connected to the same agent 🙂

When you have 45 locations, 45.000 students with BYOD and 10.000 Managed workstations, you will monitor 24 x 7 to keep everything running for your Business. Monitoring Express Route with a Backup connection is a must for your Hybrid Virtual Datacenter. Here you have more information about monitoring Express Route Circuit

Monitoring our Express Route

With this all installed in Microsoft Azure by Design, we have the policy Security First !

Microsoft Azure Security Center Investigation Dashboard

The Investigation feature in Security Center allows you to triage, understand the scope, and track down the root cause of a potential security incident.
The intent is to facilitate the investigation process by linking all entities (security alerts, users, computers and incidents) that are involved with the incident you are investigating. Security Center can do this by correlating relevant data with any involved entities and exposing this correlation in using a live graph that helps you navigate through the objects and visualize relevant information.

Microsoft Azure Security Center found also a rare SVCHOST Service on my Surface, and the ASC investigation dashboard gives you great overview of the security risk.
